IMPROVEMENT IN FANNlNG-MILLS.

Specification forming part of Letters Patent No. 203,067, dated April30, 1878 application filed February 14, 1878.

To all whom it may concern:

Be it known that I, PERRY A. PEER, of

Oomstock, in the county of Kalamazoo and State of Michigan, haveinvented a new and useful Improvement in Fan-Mill Irons, of which thefollowing is a specification:

Figure 1 is a front and a rear view of onehalf of the spider or hub.Fig. 2 is a detail section of the same, taken through the line at m,Fig. 1. Fig. 3 is a side view of the shakeriron. Fig. 4 is a top view ofthe same.

Similar letters of reference indicate corre spondin g parts.

The object of this invention is to furnish improved irons for fan-mills,which shall be simple in construction, neat, strong, durable, andconvenient in use.

A represents the hub or spider for connect.

ing the arms of the fans to the fan-shaft. The hub or spider A is castwith radial loop-sockets a to receive the ends of the arms B, and with acentral hole, M, to receive the shaft 0. The inner ends of the arms Bare cut or shouldered upon one side of their inner ends, to fit overledges formed, as shown, upon the middle part of the said hub or spider,as shown in the lower part of Fig. 2. i

The arms B are secured in place in the sockets a by nails or screws 1),driven into them at the inner side of a loop of the sockets a, asshownin Figs. 1 and 2. The shaft 0 is connected with the hub or spiderA, and made to carry said hub or spider with it in its revolution by apin, 0, passed through the said shaft, and the ends of which project toenter notches a in the side of the said hub or spiderA, as shown in Fig.2.

In putting the fans together the arms B are inserted in the sockets aand secured by the nails or screws 1). The shaft 0 is passed through theholes to and the pins 0 are driven into 1 their holes. The hubs orspiders A are then adjusted upon the shaft 0 to bring the pins 0 intothe notches or recesses a and the fans are nailed or otherwise securedto the outer ends of the arms B, which locks all the parts securely inplace. D is the connecting-rod, one end of which is pivoted to a crankformed upon the fan-shaft O. The other end of the connecting-rod D has acurved or U-shaped hook, 01, formed upon it, which is hooked into an eyeformed in the end of thelon g arm of the shaker or angular lever E. Thepeculiar form of the hook 01 causes it to work easy in its eye,

as the other end of the rod D is moved up and down by its crank. Theother arm of the lever or shaker E is made shorter, and, has an eyeformed in it to receive the hook, by which it is connected to the shoethat carries the screens. The arms of the shaker E are connected attheir outer ends by a bar, 0, to strengthen them. In. the angle of theshaker E is formed an eye which fits into the space between the two lugsformed upon the plate F, where it is pivoted or hinged by a pin, f. Thelug-plate F is secured to a post of the fanmill frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The hub or spider A, cast with radial loopsockets a,to receive the arms B, with a central hole, m to receive the shaft (3,and recesses a to receive the pin 0, that connects it with said shaft,each arm resting at the rear against a shoulder of the hub, and securedby a nail on the inside of sockets a, substantially as herein shown anddescribed.
